Abstract
The field experiment entitled “Productivity and quality of dual purpose oats (Avena sativa L.)
in relation to sowing and cutting dates” was laid out at two locations viz. Ludhiana and
Gurdaspur in randomized complete block design with twelve treatment combination i.e. four
dates of sowing October 10 (D1), October 25 (D2), November 10 (D3) and November 25 (D4)
with three cutting treatments uncut (C0), cut at 50 DAS (C50) and cut at 65 DAS (C65). Soil of
experimental field at Ludhiana was normal in soil reaction and electrical conductivity, low in
organic carbon and available nitrogen, high in available phosphorus and low in available
potassium. At Gurdaspur normal in soil reaction and electrical conductivity, medium in
organic carbon and medium in available nitrogen, high in available phosphorus and low in
available potassium. Crop sown on October 10 took minimum days for initiation and
completion of emergence at both the locations. Crop sown on October 10 (D1) and cut at 50
DAS (C50) attained significantly higher plant height at maturity at both the locations. D1 uncut
crop accumulates significantly higher dry matter at all days of observation at both the
locations. The highest green and dry fodder yield was obtained from the early sown crop cut
at 65 DAS than the 50 DAS. Crop cut at 50 DAS for fodder took minimum number of days
for regeneration than cut at 65 DAS at both the locations. Crop cut at 50 days after sowing
had better fodder quality parameters in terms of crude protein, total ash, leaf stem ratio and
digestibility (in-vitro) than that cut at 65 DAS at both the locations.The highest grain yield
was obtained from D4C0 which is at par with D1C50 at both the locations.The highest straw
yield was recorded in October 10 and October 25 sown than other dates of sowing. Seed
viability, germination, seedling length, vigour index I, vigour index II, seedling dry weight
was significantly higher in October 10 sowing crop and in uncut treatment at both the
locations. Taking fodder cutting 65 DAS from sown on October 10 generated highest
additional income at Ludhiana however at Gurdaspur taking fodder cutting 50 DAS from
October 10 sown crop.
